What is the weight of a 45.40 kg Barbell dropped on Earth?

The weight of a 45.40 kg barbell dropped on Earth can be calculated using the formula:

Weight = (mass) x (gravity)

= (45.4 kg) x (9.8 m/s²)

= 444.9 Newtons (roughly 100.09 pounds)

That's the weight of the barbell, and it doesn't matter if it was dropped. It could be on the shelf at the sporting goods store, or standing up on end in the closet, or rusting at the bottom of a huge tank of chicken soup. No matter where on Earth it is or what it's doing, it weighs 444.9 Newtons.

Calculation of Weight

When a 45.40 kg barbell is on Earth, it experiences a gravitational force. The weight of an object is the force exerted on it due to gravity. In this case, the weight of the barbell is calculated as follows:

Weight = mass x gravity

Substitute the values for mass (45.4 kg) and gravity (9.8 m/s²) into the formula:

Weight = 45.4 kg x 9.8 m/s²

Weight = 444.9 Newtons

Significance of Weight

The weight of the barbell is approximately 100.09 pounds. This weight remains constant regardless of the barbell's position or activity on Earth. Whether it is dropped, placed on a shelf, or submerged in liquid, the weight of the barbell remains the same due to the gravitational pull of the Earth.
